Abstract
The use of Self-Compacting Concrete (SCC) has grown in popularity due to its numerous advantages. However, the production of SCC is typically expensive and may have an environmental impact due to its properties requiring high fluidity, which results in high proportions of cement usage. With the advancement and evolution of the construction industry, an alternative method of producing SCC is being developed by utilizing construction waste or supplementary cementitious material (SCM). This study investigates how partially replacing cement in SCC with fly ash (at varying levels of 10%, 20%, and 30%) alongside fixed amounts of silica fume and rice husk ash (5% each) affects the concrete’s properties. Samples were cured for different durations and tested for workability (slump flow) and strength (compressive strength). Interestingly, the researchers found a link between fly ash content and the spread ability of the SCC mix, with higher fly ash leading to easier flow. This suggests fly ash as a promising material to improve SCC workability. As expected, the concrete (SCC) got stronger (higher compressive strength) over time (28 days curing) compared to earlier measurements. However, the study also found that using more fly ash in the mix resulted in a noticeable decrease in this long-term strength.
